iPhone: Evernote has released an update to its popular image annotation tool, Skitch, that includes new designs for its Mac and iPad client, as well as a brand new iPhone version.

While the iPad and Mac versions get a nice update and visual overhaul, the iPhone version is brand new. Both the iPad and iPhone version have the same image annotation features as ever so you can draw arrows on just about everything. New features, like pixelating images, and a highlighter are great additions. Skitch can also detect words in any image, making pictures of text fully searchable. As you'd expect, Skitch is fully integrated into Evernote. Check out the Evernote blog for a peek at all the new features.
